Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a shock absorber and generator for vehicles that can be applied to vehicles from light vehicles such as bicycles to automobiles and railway vehicles.

[0002]

[Prior art]

 As a conventional shock absorber, a shock absorber such as a coil spring, a leaf spring, or a torsion bar, or an air suspension is known. Hydraulic shock absorbers are also well known. However, there is no known generator that can be used as these.

[0003]

[Problems to be solved by the invention]

 In vehicles such as bicycles, automobiles, and trains, the above-described shock absorbers have been developed and improved in order to improve ride comfort.

[0004] However, in any case, the technology to be developed places emphasis on improving the ride comfort by simply absorbing vibration or impact caused by road surface irregularities or the like (of course, this is the point of view). At the same time, improvements have been made to reduce the inclination of the vehicle body when starting and braking.) However, the effective use of energy such as vibration or impact caused by the unevenness of the road surface, etc. Is not considered at all.

In the present invention, the energy such as vibration or shock that is more than wasted is converted into electric power, and a buffer effect is obtained while effectively using the electric power.

By the way, the generator mounted on these vehicles is a conventional rotary type, and a bicycle uses human power, and other vehicles use a part of the driving power of an engine as a driving body thereof. By doing so, power is generated. However, naturally, power cannot be generated unless energy for driving the driving body is prepared. Or it is impossible to generate electricity unless a person moves a bicycle.

That is, in the present invention, auxiliary power is obtained by utilizing energy such as the vibrations wasted and wasted without preparing a drive source which needs to supply energy specially. Another object of the present invention is to provide a shock absorber-generator for vehicles which can also obtain a shock absorbing function by the configuration for obtaining the electric power at the same time.

[0008]

[Means for Solving the Problems]

 Thus, in the present invention, the power generating coil and the power generating magnet are relatively combined so that the former makes a linear reciprocating motion by cutting off the magnetic flux of the latter, and the power generating coil and the power generating magnet are relative to each other. And a connecting means for connecting the power generating coil and the power generating magnet one to the vehicle side and the other to the wheel side. This is a generator that also serves as a shock absorber for the configured vehicles.

[0009] If the relative reciprocating motion between the power generation coil and the power generation magnet is linear, in practice, either the former or the latter may be configured to move. As described later, it is easier to configure the power generation magnet to reciprocate. Permanent magnets are easy to use as generator magnets.

As a specific configuration, for example, a shaft member is inserted from the upper end of the cylindrical case so as to be able to move up and down, and the former is connected to the connecting means to the wheel side, and the latter is connected to the connecting means to the vehicle body side. However, it is appropriate to adopt a configuration in which each of the above elements is incorporated.

For example, the power generating coil is disposed upright on the bottom surface of the cylindrical case, while the power generating magnet is fixed to the lower end of the shaft member, so that the power generating magnet is It is configured to be able to move up and down inside. As the power generation magnet, a columnar permanent magnet having vertical magnetic poles is employed.

Incidentally, the shaft member is provided with a guide member for guiding the shaft member up and down at the above-mentioned position. The guide member can have any configuration. For example, a bearing for slidably supporting the shaft member in the elevating direction is provided at the upper end and in the middle of the cylindrical case as the guide member. As bearings, roller bearings, ball bearings, plain bearings, etc. are selected and adopted as necessary.

On the other hand, as the limiting means, on the one hand, at the position on the bottom surface of the cylindrical case and at the position inside the power generating coil, the upper end has the same magnetic pole as the magnetic pole on the lower end side of the power generating magnet. On the other hand, a limited magnet is arranged, and on the other hand, a limited spring member is arranged on the upper part of the cylindrical case, and a flange body is protruded on an outer periphery in the middle of the shaft member. When it reaches, the flange body comes into pressure contact with the lower end of the limiting spring member, and when it reaches the lower limit, the magnetic pole at the upper end of the limiting magnet repels the power generation magnet to limit the ascending / descending range.

It is preferable that a thin sheet-like elastic material such as a sponge is adhered to the upper end of the limited magnet in some cases. Thus, it is possible to prepare for a case where the power generation magnet and the limit magnet may collide with each other due to extremely strong vibration.

[0015] Since the present invention is configured as described above, the connecting means of the power generating coil and the connecting means of the power generating magnet are separately connected to a vehicle body side or a wheel side of a vehicle.

Then, when the vehicles travel on a road or the like, vibrations generated on the wheels due to irregularities on the road surface or the like are first transmitted from the connecting means to the shock absorber. As a result, due to the vibration, the power generating coil and the power generating magnet relatively move in a linear reciprocating motion by cutting off the magnetic flux of the latter, and an electromotive force is generated in the power generating coil. Accordingly, with the generation of the electromotive force, a braking force is generated in the relative reciprocating motion between the power generation coil and the power generation magnet.

[0017] Thus, according to the present invention, the energy of the vibration generated by the unevenness of the road or the like is converted into electric energy, which serves as an auxiliary power source for the electric power used in the vehicle and the like, and acts as a shock absorber. Can be fulfilled. The relative reciprocating motion between the power generating coil and the power generating magnet is limited to a certain range by the limiting means. In addition, since the current obtained from the power generation coil is an AC current having an inconstant frequency, it is appropriate to rectify the battery by a general rectifier and charge the battery before use.

[0018]

[Embodiment of the invention]

 Hereinafter, embodiments of the invention will be described in detail based on an embodiment with reference to the accompanying drawings. 1 and 2 show an embodiment of a shock absorber-generator for vehicles according to the present invention. FIG. 1 is a schematic sectional view thereof, and FIG. 2 is a diagram for rectifying an extracted AC current to charge a battery. Or an auxiliary power supply circuit for use as an auxiliary power supply for vehicles together with the discharge current of the battery.

As shown in FIG. 1, the shaft 2 is inserted into the cylindrical case 1 from the upper end so as to be able to move up and down. The cylindrical case 1 is provided with a support cylinder 3 for supporting the shaft 2 so as to be able to move up and down at the center of the upper end thereof, and the shaft 2 is likewise able to be moved up and down at the center near 2/3 from below. The support cylinder 4 is configured to be supported by the support cylinder 4. The support cylinder 3 is supported by an upper end plate 1a for closing the upper end of the cylindrical case 1, and the support cylinder 4 is provided with arms 5, 5 protruding toward the center on the inner periphery of the cylindrical case 1. Supported by….

At the center of the upper surface of the lower end plate 1b of the cylindrical case 1, a power generating coil 6 is disposed in an upright state. On the other hand, at the lower end of the shaft 2, a columnar power generating magnet 7 is fixedly mounted so as to be able to move up and down in the power generating coil 6. The power generation magnet 7 is a permanent magnet having magnetic poles at the top and bottom, and has an N pole at the lower end and an S pole at the upper end. Further, at the position on the upper surface of the lower end plate 1b of the cylindrical case 1 and at the central position inside the power generating coil 6, the upper end has the same magnetic pole as the magnetic pole on the lower end side of the cylindrical power generating magnet 7. The lower-limit limiting magnet 8 having the N pole is provided. When the power generation magnet 7 reaches the lowering limit in this way, the N pole at the upper end of the magnet 8 and the N pole at the lower end of the power generation magnet 7 repel each other to limit the lowering limit.

On the other hand, on the lower surface of the upper end plate 1a of the cylindrical case 1, a limited coil spring 10 having a donut-shaped contact plate 9 at the lower end is arranged. When the shaft 2 reaches the upper limit, the flange 11 elastically contacts the contact plate 9 of the limited coil spring 10 to limit the upper limit.

In the drawing, reference numeral 12 denotes a connecting ring formed at the lower end of the cylindrical case 1 for connecting to a vehicle wheel side, and reference numeral 13 denotes a connecting ring formed at the upper end of the shaft 2 for connecting to a vehicle body side. It is a ring.

As shown in FIG. 2, both ends of the power generating coil 6 are connected to an input terminal of an alternating current of a bridge diode 14, and an output terminal of the bridge diode 14 is connected to a battery 15. Both poles of the battery 15 are further connected to an output terminal for outputting as auxiliary power for vehicles.

In this embodiment, as described above, the connecting ring 12 at the lower end of the cylindrical case 1 is on the wheel side of vehicles, while the connecting ring 13 on the upper end of the shaft 2 is on the vehicle body side. Use in conjunction. For example, in this embodiment, since it is small and simple, it can be used as a support for supporting a saddle of a bicycle or a support column for supporting a carrier.

When this shock absorber is used as a supporting column for supporting a loading platform, a pair of it is disposed on both sides, the connecting ring 13 is connected to the loading platform, and the connecting ring 12 is connected to the axle side. .

When the bicycle travels on the road, vibrations generated on the wheels due to unevenness of the road surface are first transmitted from the connecting ring 12 to the cylindrical case 1 of the shock absorber. The vibration of the cylindrical case 1 causes the power generating coil 6 to relatively cut off the magnetic flux of the power generating magnet 7 and reciprocate linearly. As a result, an electromotive force is generated in the power generating coil 6. On the other hand, the generation of the electromotive force generates a braking force against the reciprocation caused by the vibration of the power generation coil 6 and the power generation magnet 7. This braking force acts as a buffer.

Thus, according to this embodiment, the energy of the vibration generated by the unevenness of the road and the like is converted into electric energy, which serves as an auxiliary power source for the electric power of the lights used in the vehicle, in this case, the bicycle, and has a buffer. It can function as a device.

The lower limit of the reciprocating up and down movement of the power generation magnet 7 is limited by the magnetic repulsion between the magnet 8 and the power generation magnet 7 disposed on the bottom surface of the cylindrical case 1, and the upper limit is the cylindrical case. The contact plate 9 provided at the lower end of the limited coil spring 10 at the upper part of the shaft 1 and the flange body 11 provided in the middle of the shaft 2 come into contact with each other and are resiliently repelled.

Further, the alternating current having a variable frequency generated in the power generation coil 6 of the shock absorber described above is rectified by the bridge diode 14 and charged into the battery 15 as shown in FIG. The current charged in the battery 15 is used for various devices mounted on vehicles, similarly to the general one.

[Effects of the Invention] In the vehicle-type shock absorber / generator of the present invention, the connecting means for the power generating coil and the connecting means for the electromagnet are respectively connected to the vehicle side or the wheel side of the vehicle, respectively. . Then, when the vehicles travel on a road or the like, the vibration generated on the wheels due to the unevenness of the road surface or the like is first transmitted from the connecting means to the shock absorber, and as a result, the power generation coil and the power generation magnet are caused by the vibration. Relatively, the former cuts off the magnetic flux of the latter and reciprocates linearly, and an electromotive force is generated in the generating coil. With the generation of the electromotive force, the relative position between the generating coil and the generating magnet is reduced. A reciprocating motion will generate a braking force.

Thus, according to the vehicle-type shock absorber / generator of the present invention, the energy of the vibration generated due to the unevenness of the road and the like is converted into electric energy, which becomes an auxiliary power source for the electric power used in the vehicle and the like. In addition, it can function as a shock absorber.

Since the relative reciprocating motion between the power generating coil and the power generating magnet is limited to a certain range by the limiting means, unintended large vibrations may damage the power generating coil itself and make it inoperable. No problem.

Since the current obtained from the power generating coil is an alternating current having an inconstant frequency, the battery is rectified by a general rectifier and charged into a battery for use, thereby providing a stable DC output suitable for use. You can get it.

According to the vehicle-generator / buffer-generator of the present invention, the energy such as the vibration caused by the unevenness of the road surface during the running of the vehicles, which has been wasted until now, is effectively used. be able to. That is, the waste energy such as vibration is converted into electric power to be used as an auxiliary power supply, and a buffer action such as suspension can be obtained.

[0035] In the above-described vehicle-unit shock absorber / generator of the present invention, as a basic telescopic structure, a shaft member is inserted from the upper end of the cylindrical case so as to be able to move up and down, and the former is connected to the wheel side. In the case where a configuration is adopted in which the latter is connected to the connecting means for connecting to the vehicle body side and the above-described elements are incorporated in the connecting means, a simple structure that reliably operates can be obtained.

As a braking and cushioning structure, the power generating coil is disposed upright on the bottom surface of the cylindrical case, and the power generating magnet is fixed to a lower end of the shaft member, whereby the power generating magnet is configured to generate the power. In the case of adopting a configuration in which the coil can be moved up and down freely, it is possible to obtain a power generation effect by vibration with a simple configuration, and to obtain a buffering effect of reducing the vibration through this operation. As the power generation magnet, a columnar permanent magnet having a vertical magnetic pole is employed.

On the other hand, as the limiting means, on the one hand, the same magnetic pole as the lower magnetic pole on the lower end side of the power generating magnet is provided at the upper end at the position on the bottom surface of the cylindrical case and on the inner side of the power generating coil. In the case where a limited magnet is arranged, and on the other hand, a limited spring member is arranged on the upper part of the cylindrical case and a flange body is protruded on the outer periphery in the middle of the shaft member. When the upper limit is reached, the collar body is pressed against the lower end of the limited spring member, and when the lower limit is reached, the power generating magnet is repelled by the magnetic pole at the upper end of the limited magnet. Can be.
